Description and Introduction

Stereo, Fully Differential Class-AB Audio Amplifier The TPA6020A2 is a stereo audio power amplifier manufactured by Texas Instruments (TI). Below are its specifications, descriptions, and features based on factual information from Ic-phoenix technical data files:

### **Specifications:**
- **Output Power:**  
  - 1.4 W per channel into 4 Ω at 5 V (THD+N = 10%)  
  - 1 W per channel into 8 Ω at 5 V (THD+N = 10%)  
- **Supply Voltage Range:** 2.5 V to 5.5 V  
- **Efficiency:** Up to 87% (eliminates need for heat sinks)  
- **THD+N (Total Harmonic Distortion + Noise):** 0.1% (typical at 1 kHz, 1 W into 8 Ω)  
- **Signal-to-Noise Ratio (SNR):** 95 dB (typical)  
- **Shutdown Current:** 0.1 µA (typical)  
- **Operating Temperature Range:** -40°C to +85°C  

### **Descriptions:**  
The TPA6020A2 is a Class-D stereo audio power amplifier designed for portable applications such as mobile phones, PDAs, and portable media players. It operates efficiently with a single power supply and includes features like thermal and short-circuit protection.  

### **Features:**  
- **Class-D Operation:** Provides high efficiency and low power dissipation.  
- **No External LC Output Filters Required:** Reduces BOM cost and board space.  
- **Thermal and Short-Circuit Protection:** Enhances reliability.  
- **Low Supply Current:** 3.5 mA (typical) in active mode.  
- **Click-and-Pop Suppression:** Minimizes audible noise during power-up/down.  
- **Small Package:** Available in a 20-pin TSSOP package.  

This information is based solely on TI's official documentation for the TPA6020A2.
